Abstract (en)
[origin: EP3754641A1] A method for eliminating ghost images during AMOLED display, a display terminal, and a computer readable storage medium: when detected that an AMOLED display panel is powered on, timing a first duration for which the display panel is continuously powered on (S10); according to the first power-on duration, acquiring various gray scale compensation values of various corresponding TFTs, and according to different gray scales, determining various gray scale compensation values of various specific TFTs (S20); according to the various gray scale compensation values, adjusting the drive current of the various corresponding TFTs on the display panel (S30); thus, the drive current flowing through the TFTs remains unchanged, low costs are used, and the simple manner of implementation solves the problem of ghost images during AMOLED display.
